[fix](parquet)Parse Parquet INT96 physical type data into a no-timezone datetime.

[hubgeter]

What problem does this PR solve?

Problem Summary:
This PR fixes the semantics of reading Parquet INT96 values. Previously, INT96 was interpreted as a time zone–aware type, causing the read results to vary with the set timezone configuration.
This PR changes the behavior to always convert INT96 values to UTC, treating them as time zone–independent timestamps.

Release note

Parse Parquet INT96 physical type data into a no-timezone datetime.
